Hurst, The Range oj Diotis candidissima. 



PLATES I. AND II. 



Both photographs were taken at the western extremity of the bar 

 at Lady's Island Lake, on October 15th, 1901. 



Plate I, Looking southward across the bar. There are a few 

 plants of Euphorbia Paralias in the foreground, 

 recognisable by their dark colour in the photograph. 

 The sandy, gravel-strewn nature of the soil affected 

 by Diotis is better shown in Plate 2. The young 

 plants of Diotis approximate so much in colour to 

 the grey pebbles among which they grow, as some- 

 times to be with difficulty distinguished from them. 



Plate 2. Looking westward along the bar. The plants in the 

 foreground are rather more weather-beaten than 

 those in Plate \. The way in which Diotis mono- 

 polises the ground in this locality, stretching far 

 away into the distance, is well shown in this 

 photograph. The shrubby nature of the more 

 luxuriant plants is also noticeable.
